axWindowsMediaPlayer Exception ?

When I create an instance of my page like this :FXrealdetay formdetay =newFXrealdetay(); Exception throws like below :

ActiveX control '6bf52a52-394a-11d3-b153-00c04f79faa6' cannot be instantiated because the current thread is not in a single-threaded apartment.

Error line :this.axWindowsMediaPlayer1 =new AxWMPLib.AxWindowsMediaPlayer();

But from another form when ? create instance and show the page error doesnt throw.it works.

What can I Do?

Thanks.
